Foundations are the design primitives that are not components — the tokens every component reads from. Eleven token sets, data-driven from source so a token change propagates everywhere.
Token-system orientation — modes, schemes, the two layers.
·02Primary, secondary, status, and the full ramp set — with HEX / RGB / CMYK.
·03The two typefaces, the scale, weights, and hierarchy in use.
·04The 4px base scale — eleven steps for every gap and pad.
·05Five corner radii — soft, restrained, never sharp.
·06Shadow / surface elevation.
·07Duration, easing, and distance constants.
·08The data-density scale.
Focus-visible ring tokens.
·10Layout grid tokens.
·11Input state tokens — error / warning / success.
